isolation rate of important anaerobic bacteria from clinical specimens

it is now generally recognized that anaerobic bacteria may be involved in most human bacterial infections that follow any form of surgery or are related to those body sites that have a large anaerobic population. anaerobes must therefore be sought in a wide variety of clinical specimens. in this study, 3015 specimens of patients (1684 male and 1331 female) with periodontitis (160 cases), abcess (305), sinusitis (33) and enterocolitis (2517) wer investigated. the anaerobic isolates from patients with periodontitis were 244 cases, abscess 32, enterocolitis 42.
